  Among the unemployed doctors in countries with a large public sector of health care, there has been little interest in venturing out as private entrepreneurs. Instead, the medical profession is interested in protecting the position of doctors as employees in the public sector, which can secure their position in the division of labour in health care better than the private sector.

It can't be helped if an industry is socialised to the extent that professionals are dependant on the state. At that point the mechanics of supply and demand are affected by interference.
